T o (./ZZ whom it meg/ concern.: i

- Be'lt known that I, Meri-:u Cortas, a sub- ]ect ot' Russia (who has taken out his hrst papers), and a resident of Charleston'. in

the countv of Charleston and State of South Carolina, have invented certain new and use-ful Improvementsin Bismit-Imprinting 'of the constructions, combinations and arrangements herein described and claimed.

An object of the invention is to provide'a machine by the use of which a considerable Jiumber. of biscuits or rolls may be impi-inter'jl with a. certain adopted design at one time, lnot only'insuringa unitormit)Y in design but also expegliting the work.

Another object of the invention isto pro.- vide a tray having a plurality ot pockets into each of which the. biscuit orroll dough is placed, said tray' then being slid in place upon the base of the.` machine whereupon lthe presser head which carries the dies is 'lowered so that the desired imprint is made in the dough.

Other objects and advantages appear in the following specification, reference being had to the l accompanying drawings, in which- Figure 1 isa front elevation of the improved imprinting machine.

which the tray rests when in the position for imprinting the biscuits or so-called rolls.

For .the purpose of insuring t-he proper positioning of the tray 3 inrcspect to the presser head fche base 1 carries a pair of guides 5 With bent flanges 6 which enter grooves T at the sides ol the tray. The base` 1 also carries a pair of cleats 4i3 (Fig. 2) i which extend across the top 2 and limit the movement` of the tray when slid upon thegnides. The tray ,carries a handle 9 by means of which it may readily be moved back and forth.

This shape has been adopted in this par- 3 as well as the. number of pockets l1G em- It is to be observed that the traj\ v is of a regularyfpolvgonal shane.

ticular instance t-o accommodate 19 dough- .t5 It should be. understood, hom.

ploved maybe varied as ma.)v he.r found neces sar \v or desirable. More` or less pockets may be used Without-` aii'ecting the invention.`

4It is the purpose of the machineto imprint a design upon small masses of dough placed in each of the pockets 10. The die 11 (Figs. 7 and 8) used in this lparticular instance produces a peculiar crossed orease identifying the finished product With what is commonly known as a. `Vienna roll and sometimesl called a Kaiser roll. Each lof the dies 11 is precisely alike and the description of onewill answer for all.

The die 11 is composed of a circular plate 12 which carries a pluralit)Y of blades 13. The peripheral edges ot the lblades fall short of the pcrpher)7 of the: plate 12 thereby leaving a. cleat' .tiange which is adapted to seat uponthe top of the tray 3 when the squeezing out of the dough pockets.l It is.

arl are curved in opposite directions. Y vThey also stand at.- a` slightV inclination to the platen ll'and the1eb \"'produce a die which is peculiarly. adapted to the particular purpose in mind.

Aliolt 1l holds the die in place, This bolt is screwed through the head l Iind into the die. F ignre 4. It. should be pointed out that` in practice the dies 11 may be made integral with the presser head 4, that is toisay both The arrangement is clearly shown in 1 parts may be cast in one.y 'l-Iowever, it is anticipated that the particular construction ,Shown has the advantage of permitting the replacement rof any one of the dies should a breakage occur. This could not be readily done iff all of the dies were cast integrally with the presser head.

Situated at the sides of the *base 1 are guide tubes 15. Each of tlieseis mounted upon a plate 1G which Vis mounted in a recess 1T in the base 1. where they are held in place by bolts 18.y .Each of the plates includes a bearing 19 (Fig. 9) which enters the hollow base 1 through a suitable openingr 20. The bearings 19 are for the purpose of supporting a-rod 21 by which a pair of cranks 22 are carried.

The-cranks .are clamped in place as at 23 (Fis- 5)-v Movable in the guide tubes 15 are. carrier rods 9.4 which support and carrytlie presser` head 4 by means of brackets Q5; These brackets are pinned at` 26 orotlierwise suit-g `4ablysecured to the rod 2l; The brackets extend over the ypresser head 4 (Fig. to

which they are suitably secured by means of bolts i7. Extending from one to thc other of the carrier rods 2l' at the bottom (Fig. 4) is a span rod 28. This rod operates in ,slots 29in the sides of the base 1. lt is rigidly secured to the rods 24 by any suitable Vmeans, nuts 30' being shown to Lio illustratca conventional fasteninff.

A rest 31 extendingr across the lbase l supports a pair of springs which press up* ward on the rod QS and thus keep the. presser head el in 'a normally raised position. The

span rod :2 8 may be provided' with lugs 33A so that t-lie springsmay not slip off. Similarly, the rest 3] may be provided with rccesses 34 to be occupied by the springs.

.Tournaled upon the base l somewhat in advance of the span rod QS and the rest 31 is a lever rod 35 which carries a yoke or handle 36 (Fig. 1') by means of which the machine is operated. The yoke. has a centrally bent port-imi 37 (Fig.V 2) which more proper-ly forms a handle intended to bew' grasped .b v the operator in pullingfthe `yokev forward. The rod 35 carries apair of levers 3S (Fig- 5) of which only one .issho'wn in the diawings. i connected with a correspondingr crank 2.2

-liy means of a link 39. The linksare made i-iitwo parts, one being'screwed within the other. Upon desiring1r to adpist the links Y for length one of the' pivotal bolts may be removed and replaced after the desired' adpistiiient has been made.4 Springs 40. at-

r .36 to the uprightposit'ioii by virtue of press- Each of the levers `I3S isv Although A5 on to'p of the top 2. The cleats 8 (Fig. 2)

limit Athe movement of the tray.` The parts are so made thatv the pockets 10 will come exactly beneaththe dies 11.

T he movement of the presser head 4 is perfectly rectilinear,` this 'being insured by the rigid tubular guides 15 and the carrier rods Q4' which slide therein. Proper registration of the dies 11 with the dough pookets 10 make this kind of movementnecessary. v

Upon pulling forward on the yoke-36 the lever rod will correspondingly rock forward, pulling down'onthe links 39 so that the cranks 2:2 (Fig. 5) press down upon 'the span rod Q8 and pulldown onv the carrier rod 2l producing the rectilinear movement of tbc head 4 previously spoken of.' The blades 12 of the dies then enter the pockets- 10. The flanges 12 of the dies contact the top of the tray 3 (liginti)V thereby serving tov close the dough pockets land prevent. any dough from squeezing out. i v

Upon releasing the yoke 3G the .combined influence of the springs 82 and 40 will cause the yoke, presser head and 'associated arts to ret-urn to the original position, w iereupon the tra'y 3' can be removed from the machine'by pullingon the hand-le 9. The imprinted dough blanks are thenreinoved,

the pockets 10am-refilled and thetray is1 replaced for a repetition of the foregoing operation. t

The. use of this machine 'has numerous advantages. 'ltis tok be observed that ay considerable number of dough blanks are' imprinted atf-one time. In the present instance, one operation of the machine imprints 19 blanks. This alone, is a decided advance over the prevalent method of im# printing!r each dough blank separately. The. use of the machine. also insures absolute uniformity in iiiiprintintir each of the blanks.

vvThe work of preparingr the blanks for baking is vgreatly facilitated.
